P.W.D. Office Technical Support Engineer Interview Questions, Process, and Tips

Connecting to a database has multiple options depending on the type of database and programming language used.

• For SQL databases, options include using JDBC for Java, ODBC for C++, and ADO.NET for C#.

• For NoSQL databases, options include using MongoDB's driver for Python or Node.js.

• ORMs like Hibernate and Entity Framework can also be used to abstract away the database connection details.

• Connection strings are used to spe...read more

Cement is a binding material used in construction to hold together different materials.

• Cement is made by heating limestone and clay in a kiln.

• It is used to make concrete, mortar, and grout.

• Different types of cement are used for different purposes, such as Portland cement for general construction and high-temperature applications.

• Cement can also be used as a decorative element, such as in polished concrete floors.

There are different types of cement such as Portland cement, white cement, rapid hardening cement, etc.

• Portland cement is the most commonly used type of cement in construction

• White cement is used for decorative purposes

• Rapid hardening cement is used for quick setting of concrete

• Other types of cement include sulfate-resisting cement, low-heat cement, etc.

OPC and PPC are types of cement used in construction.

• OPC stands for Ordinary Portland Cement and is commonly used for general construction purposes.

• PPC stands for Portland Pozzolana Cement and is used for specialized construction purposes such as marine structures and hydraulic structures.

• PPC has a lower heat of hydration and is more resistant to chemical attacks than OPC.

• OPC has a higher compressive strength than PPC.

The density of cement varies depending on the type and brand, but typically ranges from 1.13 to 1.5 grams per cubic centimeter.

• Density of cement is measured in grams per cubic centimeter

• The density of cement can vary depending on the type and brand

• Typically, the density of cement ranges from 1.13 to 1.5 grams per cubic centimeter

Dependency injection is a design pattern where the dependencies of an object are provided externally.

• Dependencies are objects that a class needs to function properly

• Dependency injection allows for loose coupling between objects

• There are three types of dependency injection: constructor injection, setter injection, and interface injection

• Example: Instead of creating a new instance of a dependency within a class, the depe...read more

Steam API is a set of tools and resources for game developers to integrate Steam features into their games.

• Steam API provides access to features such as matchmaking, achievements, and user profiles.

• Developers can use Steamworks SDK to integrate Steam features into their games.

• Steam API also allows for in-game purchases and microtransactions.

• Examples of games that use Steam API include Counter-Strike: Global Offensive a

HashMap is a data structure that stores key-value pairs and uses hashing to retrieve values quickly.

• Hashing function is used to convert the key into an index of an array where the value is stored.

• Collisions occur when two keys have the same hash value, which is resolved using separate chaining or open addressing.

• HashMap uses an array of linked lists to handle collisions.

• The load factor determines when the HashMap shoul...read more

Compile time polymorphism is achieved through function overloading and templates.

• Function overloading allows multiple functions with the same name but different parameters.

• Templates allow generic programming by defining functions or classes that can work with different data types.

• Examples of function overloading include cout<< for different data types and sqrt() for float and double.

• Examples of templates include vector
